    Dave, I would start off with a coil that has no core as that will take the permeability of the core out of the equation.

    Let's start with a coil where you have 12 single strands, none of them connected together.

    Then measure R and L for a single strand.

    And measure C. If your meter reads a "1" on all scales, put an external capacitor in series with the coil. This will have to be trial and error, but start off with something like 100nF. Measure it with your meter first and write down the number (as we need an accurate measured value of the external cap). Then connect it to the coil in series and re-measure the capacitance. If it goes down to about half the measured value (like around 50nF), you know your external cap is in the right ball park. If it doesn't change much, use a different value, probably best to go up in value, like 220nF or 470nF, etc. As long as you see a reasonable change in value, we will be able to calculate the capacitance of the coil.

    Then repeat this measurement, with 2 strands in series (leave the other 10 strands unconnected). This should give a measurement of 4*L for inductance and 2*R for resistance. For capacitance we will have to see what it does, but I would expect it to go down. You might need to change the external cap as well to half its value.

    Then repeat this measurement, with 2 strands in parallel (leave the other 10 strands unconnected). This should give a measurement of 1*L for inductance and 0.5*R for resistance. For capacitance we will have to see what it does, but I would expect it to go up. You might need to change the external cap as well to double its value.

    So for each case record: R, L, C of external cap, C of external cap in series with coil

    Maybe do this for the above cases first, then I will do some calculations.

    pmgriphone,

    I am headed to the basement for the day and will start doing that testing.

    I am a (diet) coke addict. Several every day. So I'm going to slowly phase that out over the next month as I go through the supply I already purchased. Thanks for the advice. I have tried pretty much everything, including the monthly injections of Amovig, which work, but I hated the dang needles so I discontinued it. When I have a bad one, I will throw up all day long, so I always have a small clean bucket next to my bed. Fun times.

    I had a go at the inductance. The series coil I estimated at 1000 turns, coil diam. 30mm, coil length 75mm.Air core.
    I made that to about 10mH. 3 in parallel 3.3333 mH. I've no idea what the permeability of a core material might be.
    ​​​​​​​Nice to hear someone else's idea.

    Thanks for clarifying all that Alex and Dave. Let me think about this a little more to come up with a method for determining L and C based on winding configuration.

    Dave, please do verify if your LRC meter shows a "1" even on the highest uF capacitance setting. If so, I believe that this is caused by the fact that the meter sees a short through the wire because of low resistance (since it is a coil, not a cap).

    The way to circumvent this is to put a capacitor in series with the coil like Alex did. Question is if you have some capacitors laying around that you could put in series with the coil. If the capacitance we want to measure is in the 0.1uF to 10uF, you would need series capacitors of about the same size to put in series. These should be caps without polarity (so non-electrolytic).

    Lastly Dave, with respect to your migraines: I have been tormented with migraines since I was a teenager. Indeed, when those come up, I would lock myself in a dark room and sleep all day long. What I have come to realize over the years is that caffeine and lack of sleep is the biggest trigger for migraines. I used to drink lots of caffeine (either in coffee, tea, coke) when I was younger. When I got older and started drinking less caffeine, I noticed that I would end up with a migraine if I hadn't drunk coffee for a few days. Typically if I hadn't drunk coffee for a couple of days, the migraine would show up on the second or third day after my last cup of coffee.

    Hence I have cut out all caffeine intake now. I also make sure I sleep enough and relax enough (I do daily meditation; check out https://en.falundafa.org/ which is completely free of charge and has done much good for me). My migraines have pretty much completely disappeared. Sometimes I still feel like a coffee and I will drink a single cup, but spot on, after 2-3 days I will then have a migraine again.

    Hope this helps.

    I am curious to know what the capacitance, inductance and resistance
    no I only wind coils and try them. I have a litz winder and a 60 coil winder. Just keep on winding till it works right. 99% perspiration.

    It will, Mr. Dave, it will have less voltage and more amperage, the good thing is that it has more magnets, and it can compensate for more of the two magnitudes.

    I remember with the 12 wire coil, I left them all in parallel, I turned on the 12 volt car light at 1.5 amp. When I put them all in series, I took a discharge whip, also with a configuration of 4 wires in series, to 3 in parallel, to obtain around 130 volts, I put a transformer from 120 to 12 volts, and turned on the bulb 12-volt, 1.5-amp car power, so you can reconfigure the connections according to what you want to get, or what you need.

    My original coil had 3strands of 1,000 feet (with 18" on each end to make connections) It would "speed up under load" with my 10 1/2" rotor that had six 2" neodymium magnets on it at 2800 RPM. When I brought my generator to this forum I was very aware that people would take whatever junk they had lying around and claim they had replicated it and were not successful. Who knows how many magnets they would have on THEIR rotor. So I recommended they build coils with the same 3,000 feet of wire, but in 12 strands instead of only 3. This would give them more options. They could try 2 strands of 6 in series. Or 3 strands of 4 in series. Or 4 strands of 3 in series. Or even 6 strands of 2 in series. It gave them a better chance of stumbling across a frequency where they would see the effect. The coil I was measuring has 3 strands of four in series. The one I will measure tomorrow has just 12 strands in series. I can wire another one in a different configuration. I could put all 12 strands in series for instance. I have, I believe, 8 coils wound that have 12 strands on them. But ONE of them has a ferrite core.

    With 22 magnets on my new rotor, I may be able to go with 6 strands of 2 in series and still get the effect. That would be nice. I would love to see a lower voltage and more amps. Let me know what you want me to set up I have all day tomorrow. Unless of course I wake up with a migraine. Then I am sleeping ALL DAY. It happens far more often than I would like.

    Okay. pmgriphone

    The connection that is made in this way in multiple wires in series and parallel, helps us with more capacitance in the coil windings, the series connection is made in the following way, each output wire is connected with another input, It can be various configurations of series and parallel, this type of connection is already well explained in this forum, it is about the coil having more capacitance between its windings, to achieve the acceleration effect or null effect, it has been investigated by the Mr. Dave, Sr, Mikey, and by your server, and by other researchers, it is about achieving greater efficiency in the generation,

    In this type of coil there is an effect and it is important to investigate and experiment to improve the generation, in my case I am not talking about over unity, about free energy, I am only talking about achieving better efficiency, the tests will show us what is you get from these projects.

    Thanks for clearing that up Alex. I was wrong in thinking that all 12 strands were in series.

    If you wire everything in series, resistance is only dependent on the total length of the wire. 20.39ohms/1000ft for AWG #23. L and C will change depending on how you wire the strands, so you will need to measure that for each wire configuration. L will also depend on the core material (e.g. air/iron/ferrite). More turns is typically more inductance (quadratic relationship with number of turns if wired in series). Capacitance needs to be measured.

    The resistance readings are correct those of Mr. Dave and the one I measured, if wire # 23 were 3000 feet it would directly measure what you comment, but please read, 12 wires, 253 feet, 4 connected in series, gives 3 connections in parallel, thanks if you are helping with the calculations, we will do it too, we will get involved in making them

    I had absolutely no time last night or this morning to work on this stuff as I was under a deadline to get some things done before a contractor comes tomorrow morning. But I made it, and now I am drinking margaritas and waiting for my wife to fix dinner. I'm taking all day tomorrow off from house remodeling, except for meeting with the contractor in the early AM, so I can do whatever tests need to be done tomorrow. I plan on testing the output of some different coils, putting together my permalloy coil, and possibly winding a coil or two. So I will do whatever tests you want me to do. I have several different meters, so I can take readings with more than one. I thought the LCR meter was the most accurate, but who knows. I have eight or so coils wound, so I will set it up so that I can measure L,C and R on all of them at the same time, so there is a comparison of how accurate they are wound. Since all are wound by hand.

    All the coils are wound with 12 strands of #23 each 253 ft in length
    Resistance should not change no matter how they are wound, should it?
    Capacitance will change depending on how the wires in parallel are connected in series.
    Inductance is MOSTLY dependent on number of turns isn't it? (I know space between turns is also important.

    I believe I have a coil with a core in it that has 3 strands of #23 each either 800 or 1,000 feet long. I can tell the difference once I find the coil because 3,000 feet of #23 wire FILLS a coil when you don't have a professional coil winding machine.
